I am a plant with a complex life cycle, alternating between two distinct forms, one of which is often seen in damp, shaded environments. My 'leaves' are actually called fronds, and I reproduce through spores rather than seeds. I don't flower, and I've been around for a very long time, with fossil records dating back hundreds of millions of years.

1. I am a vascular plant, but I do not produce seeds or flowers.
2. My leaves are called fronds and are often divided into many smaller segments.
3. I reproduce through spores released from structures on the underside of my fronds.
4. I am often associated with ancient forests and damp, shaded habitats.
